Title: Applying plastics coating to glass vessels esp bottles - using two successive holders to prevent coating on holder hardening
IPC: B05B5/08
Filed: 1974-12-27
Abstract: A plastics coating is applied onto a glass vessel using aholder to support the vessel; two holders are used in succession, the first for supporting the glass vessel while it is in the coating zone, and the second for supporting it while it passes through the hardening zone. The first holder, after the vessel has been removed from it, is pref. then used for supporting a second vessel, esp. after the adhering plastics has been removed from the holder, in particular by blasting it with a gas or air jet. Used for modern coating procedures where a thin plastics coating is applied to a vessel, e.g. a bottle, to prevent crack initiation at the surface. The use of a separate holder for the vessel while it is passed through the hardening zone means that there is no holder which becomes progressively coated with ever thicker layers of hardened plastics. The coating is applied, e.g. as a powder, using electrostatic application of dry plastics. Where the vessel is a bottle, the holder grips it by the neck.

Title: Drying gases by passing through drying agent - with periodic regeneration automatically controlled, ensuring complete drying
Inventor: BERNARD GERARD
IPC: B60T17/00
Filed: 1975-12-09
Abstract: Drying a compressed gas, by passage through a drying agent, incorporates blowing a fraction of the gas previously compressed and dried, through the drying agent, and periodically regenerating the agent. Each compression period is followed by a regeneration period. The periods of compression (T) and regeneration (t) are measured and t is regulated as a function of T, so that the amt. of water removed during the sum of the periods Epsilon t is equal to that absorbed during the sum of the compression periods. Epsilon T. The periods are measured by the counting of the pulses emitted for that purpose and recorded for the periods T as positive at the rate of one impulse per n seconds and for the periods t as negative at the rate of one impulse per nk' seconds. k' is the constant in the equation Epsilon t - k' Epsilon t, determined experimentally from v = kQ where Q = vol. of gas in the compressed state, v= that of the gas required for regeneration, at the press. at which regeneration takes place, the gas flows being constant. The regeneration is stopped when the two counts of impulses cancel one another.

Title: Continuous vacuum filtration band - has rollers rotating on bearings on one side only, allowing max. vacuum application
IPC: B01D33/04
Filed: 1976-11-26
Abstract: The invention concerns a continuous band for filtration under vacuum, consisting of an endless band which carries filter material and which is fitted with suction channels placed one behind the other and connected to a longitudinal gutter at the back of the band, and having connections on their lower surface for filtrate and air. The driving, return and supporting rollers by which the band circulates have a bearing on one side only. The gutter and the vacuum connections may be on one side of the band, or they may be in the middle of the band, with the rollers on both sides of the band. The band is divided into vacuum zones and each zone is connected individually by a pipe to a vacuum pump through a control head. There are tensioning devices on the pipes and guide elements. The filter band occupies less space and is more efficient than existing filters. The suction chamber can be kept at reduced press. over the whole length of the filter system. The problems of fluid-tightness are overcome, so that the max. suction press. of the vacuum pump is available on the filter. The filter band has a longer life and it can be shorter because it is more efficient.

Title: Dispositif d'examen par rayons x, comportant une chaine de television equipee d'une memoire
IPC: A61B6/00
Filed: 1977-07-07
Abstract: Dans un dispositif d'examen par rayons X muni d'une chaîne de téélvision équipée d'une mémoire à disque(s) d'enregistrement d'image, les signaux de déviation du tube d'enregistrement d'image de télévision et les signaux de commande de ladite mémoire sont synchronisés par intermédiaire du réseau d'alimentation. Lors de l'enclenchement du générateur haute tension, ce réseau est soumis à une charge inductive. De ce fait, par suite des différences de phase provoquées de la sorte, la synchronisation est affectée de défauts. Cela conduit à des distorsions dans une image de monitor, qui est formée sur la base de l'enregistrement par l'intermédiaire de la mémoire. Du fait qu'un certain temps avant et après l'enclenchement et le déclenchement du générateur haute tension, l'on découple la synchronisation par rapport au réseau d'alimentation on a empêché les défauts d'enregistrement. Application à l'appareillage radioscopique utilisé en médecine.
